CONTAINER.

Application filed September T 0 all whom t may concern:

Be it known that l, STEPHEN M. WALKER, a citizen of the United States, and a resident of Oak Fark, in the county of Cook and State of lllinois, have invented certain new and useful lmprovements in Containers, of which the following is aspecitication.

My invention relates to new and useful improvements in containers, and has for its object to provide a container Comprising a permanent outer member and a replaceable inner member carrying the material, and cooperating means on said members for forcing the material out of the inner member.

Another object is to provide device of this kind which may be replenished by inserting a clean, full inner member for an empty one, thus enabling the user to dispense the material and refill the device without soiling his hands.

Other objects will appear hereinafter.

The device is especially adapted to contain and dispense lubricants used in the automobile industry, somewhat in the manner of a grease gun, but it is also very useful for containing and dispensing cold cream and any other plastic toilet articles. 1t is well adapted for use with plastic materials but is also very useful for holding and dispensing liquid substances.

rlhe invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specication, and in which, y

Fig. 1 is a sectional view of the device showing a threaded tube;

Fig. 2 is a modified view showing a smooth tube with a threaded end, the tube being shown partly in section;

Fig. 3 shows the easing in section, and the tube forced partly into the shell;

Fig. 4 is a view from the discharge end of the device shown in Fig. 1; and

Fig. 5 shows a. modified manner of hold ing the neck of the tube against rotal ion in the cup of the casing.

The device or container consists of a permanent outer member or casing and a collapsible inner member or tubecontaining the, material, and co-operating means on said casing and tube for forcing the material out of the tube.

The casing comprises a cylindrical in em 3, 1921. Serial No. 498,293.

I ber or shell` 10 which` is provided with threads on the interior from the lower end to a short distance from the discharge or upper end thereof, the wall at this unthreaded upper portion 11 being made so as to provide an enlarged space 12 therein preferably in the form of an annular chamber. A laterally extending outer flange 13 is provided at the upper end of the shell 10 to engage an inwardly-extending flange 14 on a sleeve 15. |The sleeve 15 is threaded on 'the inside to engage threads on the out side of a. cup 16, and the flange 13 of the shell is held between said cup and the flange 1d of the slee-ve, whereby the shell 10 is held rotatably in posit-ion on said cup and sleeve. The external surface of the outer member or shell 10 hasbeen shown smooth but may be of any suitable design or even enclosed in a suitable ornamental covering. rllhe inner member or tube 18 is composed of pliable material such as tinfoil, pliable paper, or any suitable substance, and is p-rovided with a threaded, rigid bottom member or cap 19 which is fastened into the lower end of the tinfoil of the tube in any convenient manner, so as to firmly adhere thereto, as shown in Fig. 1, or so as to form a substantially integral mass therewith, as shown in Fig. 2. The surface of the tube may be threaded from top to bottom,y as shown in Fig. l, or may be threaded only the distance of the enclosed cap 19 and be smooth over the remaining distance, as shown in Fig. 2. The cap is made rigid and preferably of metal whereby it stiffens the bottom of the tube and prevents the pliable material of the tube from collapsing at the lower end or stripping the thread, or taking any other but the desired form, while the tube is being forced inward in the shell.

Means is provided for collapsing the tube 18 and forcing the material out of the tube through its neck 20.` This means, in addition to the co-operating threads on the tube 5, yor may be done bythe use of pins or projections on the top of the tube which lit in openings or depressions on the inner face of the cup, or 1n any convenient manner.

The threads on the neek QO'Vand on the cup i6 and the sleeve l5' are preferably riglit hand threads, While those on the cap and in the shell are left hand-threads, and in either case the threads on ther neck and @up and sleeve must be reversed to the threads' on the cap and on the interior of the shell, in order that the tubeavill 'remain lifted on the cup While the shell is being rotated to eollap'sethe tube and torcethe'niaterial ont 'of it.
